Here is a step-by-step guide on how to use a multimeter:

1. First, set the mode to V with a wavy line for AC voltage or to the V with a straight line for DC voltage.
2. Connect the red probe to the positive side of the component and the COM probe to the other side.
3. Read the value on the display.
4. To measure resistance, set the meter to the highest R x value possible and zero the meter.
5. Hold a probe in each hand and read the meter.
6. Squeeze both probes tightly to reduce resistance.
7. Wet your hands and hold the probes again to further reduce resistance.

Before using a multimeter, it's important to learn the fundamentals of electricity, including voltage, amperage, and resistance.
